Studies on the associations between the nitric oxide synthase gene (NOS3) Glu298Asp polymorphism and hypertension status or blood pressure (BP) levels have had inconsistent results. Potential moderating influences of ethnicity, sex, and obesity on the effects of the NOS3 polymorphism have not been examined. We evaluated the influence of these factors on associations between the NOS3 polymorphis...
One of the most striking features in autosomal dominant polycystic kidney disease (ADPKD) is the difference at onset age of end-stage renal disease (ESRD). Modifier genes may play a role in this phenotypic variability. The mutated nitric oxide synthase 3 gene (NOS3), have a modifier effect on the severity of ADPKD by impairment of NOS3 activity and decreasing of renal vascular nitric oxide prod...

This review examines the association of a subset of endothelial nitric oxide synthase gene (NOS3) polymorphisms (Glu298Asp, intron 4, and -786T>C) with cardiovascular disease. The Glu298Asp polymorphism within exon 7 is the only common nonsynonymous variant. The variants have been associated with low plasma nitric oxide concentrations and reduced vascular reactivity; difficulties in measuring t...
A significant phenotypical variability is observed in autosomal dominant polycystic kidney disease (ADPKD). ADPKD is associated with altered endothelial-dependent vasodilation and decreased vascular production of nitric oxide (NO). Thus, ENOS, the gene coding for the endothelial nitric oxide synthase (eNOS), could have a modifier effect in ADPKD. In order to test this hypothesis, we genotyped 1...
BACKGROUND The dialysate of patients on peritoneal dialysis (PD) is used to determine the concentration of growth factors and cytokines, and as a source of resident peritoneal cells for subsequent culture experiments. We hypothesized that the cells contained in spent dialysate samples obtained at the time of the peritoneal equilibration test (PET) and subsequently stored may represent a source ...

Essential hypertension has a genetic basis. Accumulating evidence, including findings of elevation of arterial blood pressure in mice lacking the endothelial nitric oxide synthase (eNOS) gene, strongly suggests that alteration in NO metabolism is implicated in hypertension. There are, however, no reports indicating that polymorphism in the eNOS gene is associated with essential hypertension. We...
Objective: To examine the effects of two polymorphisms of the endothelial constitutive nitric oxide synthase (ecNOS) gene, 4a/4b(A:B) located in intron 4 and Glu298Asp(G:T) located in exon 7, on the development of acute coronary syndromes (ACS). Methods: 164 patients with ACS and 142 control participants were investigated for genotype and conventional risk factors. Genotype was determined by po...
